Tableau SCA-C01 Exam With Confidence Using Practice Dumps

In a high-availability (HA) Tableau Server setup, theRepository(PostgreSQL) has an active and passive instance. Failover occurs if the active Repository fails. Let’s dive into the process:

HA Setup:

Two Repository instances across nodes (active/passive).

Failover switches to the passive instance if the active one becomes unavailable (e.g., crash, network issue).

Cluster Controller:

Role: Monitors all processes (e.g., Repository, File Store) across nodes, detecting failures via heartbeats and status checks.

Failover Decision: If the active Repository stops responding, Cluster Controller initiates failover, promoting the passive instance to active.

Coordination: Works with Coordination Service (ZooKeeper) to update topology but makes the initial detection call.

Option A (Cluster Controller): Correct.

Why: It’s the watchdog process, constantly monitoring Repository health and triggering failover when needed.

Option B (Coordination Service): Incorrect.

Role: ZooKeeper maintains cluster state and coordinates topology updates post-failover, but doesn’t detect the failure—Cluster Controller does.

Option C (Gateway): Incorrect.

Role: Routes client requests—unrelated to internal process monitoring or failover.

Option D (Backgrounder): Incorrect.

Role: Executes background tasks—no involvement in Repository failover decisions.

Why This Matters: Understanding failover ensures HA reliability—Cluster Controller is the linchpin for resilience.

Tableau Server uses internal secrets (tokens) for secure communication between its processes (e.g., Repository, File Store). These are automatically generated during installation and can be regenerated if compromised or for security maintenance. The command to update these is:

tsm security regenerate-internal-tokens: This regenerates the internal security tokens, ensuring all processes use the new tokens after a restart.

Option C (tsm security regenerate-internal-tokens): Correct. This is the documented command for updating internal secrets.

Option A (tsm data-access caching set -r 1): Incorrect. This command configures caching behavior, not security tokens.

Option B (tsm licenses refresh): Incorrect. This refreshes license data, unrelated to internal secrets.

Option D (tsm security validate-asset-keys): Incorrect. This validates encryption keys for assets, not internal tokens.

Table recommendations in Tableau Server suggest popular tables and data sources to users when they create new content in the web authoring environment. This feature is enabled by default but can be disabled at the site level.

Option A (Disable the option using the site Settings page): Correct. A site administrator can disable table recommendations by navigating to the site’s Settings > General page in the Tableau Server web interface and unchecking the option "Enable table recommendations." This prevents users on that site from seeing these suggestions, offering a straightforward UI-based solution.

Option B (Use the command: tsm configuration set -k recommendations.enabled -v false): Incorrect. There is no recommendations.enabled key in the TSM configuration settings. This feature is managed per site, not server-wide via TSM.

Option C (Publish data sources only to projects with permissions locked): Incorrect. Locking permissions restricts access but doesn’t disable the recommendation feature itself. Users with access would still see recommendations.

Option D (Disable the option using the server Settings page): Incorrect. Table recommendations are a site-specific setting, not a server-wide setting. The server Settings page (via TSM) controls global configurations, not this feature.
